3M™ Cold Shrink QT-III 7640-S, 7650-S & 7660-S Series Termination Kit includes a 1-piece, skirted termination. It ensures a pliable, tight seal for jacketed concentric neutral and concentric neutral power cables. The conjunction of high dielectric-constant material and silicone rubber insulation allows the termination to withstand voltages of 5 to 35kV.
3M™ Cold Shrink QT-III 7640-S, 7650-S & 7660-S Series Termination Kit is designed for terminating medium voltage power cables. The UV stable, track-resistant, silicone rubber insulation of the termination has a hydrophobic property and offers a long-lasting service life while minimizing leakage currents in wet conditions. The lower surface stress, high dielectric-constant material offers an optimized BIL performance while ensuring a leak-proof, compact fit. IEEE Standard 48 Class 1 Approved for outdoor, weather-protected applications.
